This lesson can be taught with only the PowerPoint presentation and worksheet handouts. Introduction MI Introduction (LSI Quadrant I): Having sharp skills in number systems will aid you in your career as an IT professional. With the ability to convert numbers without the use of a calculator, you will be able to quickly and easily solve problems that may arise. Computer systems use the binary numbering system to operate. Why do you think binary is referred to as the “natural” numbering system for computers to accomplish their tasks? [Computers and networking equipment use binary numbers, a series of BITS (short for binary digits) that are either ON (a binary 1) or OFF (a binary 0). They are encoded internally in the PC on microchips and on the computer motherboard’s bus as electrical voltages]. Understanding binary numbers and how they relate to decimal numbers is critical to understanding how computers work internally. Outline MI Outline (LSI Quadrant II): Instructor Notes: 1. Introduce numbering systems to students using a PowerPoint presentation. a. Introduce the students to the base 10 numbering system (decimal). b. Introduce the students to the base 2 numbering system (binary). c. Introduce the students to the base 16 numbering system (hexadecimal). d. Compare and contrast decimal and binary counting. e. Demonstrate decimal to binary conversion [two methods]. f. Demonstrate binary to decimal conversion [two methods]. g. Introduce hexadecimal to decimal conversion. h.

  • Binary and Hexadecimal
    Binary and Hexadecimal Binary and Hexadecimal Introduction This document introduces the binary (base two) and hexadecimal (base sixteen) number systems as a foundation for systems programming tasks and debugging. In this document, if the base of a number might be ambiguous, we use a base subscript to indicate the base of the value. For example: 45310 is a base ten (decimal) value 11012 is a base two (binary) value 821716 is a base sixteen (hexadecimal) value Why do we need binary? The binary number system (also called the base two number system) is the native language of digital computers. No matter how elegantly or naturally we might interact with today’s computers, phones, and other smart devices, all instructions and data are ultimately stored and manipulated in the computer as binary digits (also called bits, where a bit is either a 0 or a 1). CPUs (central processing units) and storage devices can only deal with information in this form. In a computer system, absolutely everything is represented as binary values, whether it’s a program you’re running, an image you’re viewing, a video you’re watching, or a document you’re writing. Everything, including text and images, is represented in binary. In the “old days,” before computer programming languages were available, programmers had to use sequences of binary digits to communicate directly with the computer. Today’s high level languages attempt to shield us from having to deal with binary at all. However, there are a few reasons why it’s important for programmers to understand the binary number system: 1.

  • Unit - 4 Instruction Set Architecture
    Unit - 4 Instruction Set Architecture Instruction Set: • Instruction set is the interface between hardware and software. • The instruction set provides commands to the processor, to tell it what it needs to do. • The instruction set consists of addressing modes, instructions, native data types, registers, memory architecture, interrupt, and exception handling, and external I/O. • The instruction set, also called ISA (instruction set architecture), is part of a computer that pertains to programming, which is basically machine language. Example: An example of an instruction set is the x86 instruction set, which is common to find on computers today. Different computer processors can use almost the same instruction set while still having very different internal design. Both the Intel Pentium and AMD Athlon processors use nearly the same x86 instruction set. An instruction set can be built into the hardware of the processor, or it can be emulated in software, using an interpreter. The hardware design is more efficient and faster for running programs than the emulated software version. Examples of instruction set ADD - Add two numbers together. COMPARE - Compare numbers. IN - Input information from a device, e.g., keyboard. JUMP - Jump to designated RAM address. JUMP IF - Conditional statement that jumps to a designated RAM address. LOAD - Load information from RAM to the CPU. OUT - Output information to device, e.g., monitor. STORE - Store information to RAM. Choice of Instruction Set: An instruction set can be defined as a group of instruction that a processor can execute to perform different operations. On the basis of complexity and the number of instruction used the instruction set can be classified as • Complex Instruction set • Reduced Instruction set Complex Instruction set The complex instruction set is the set of instruction which includes very complex and large number of instructions.

  • Java Native Interface Application Notes
    Java Native Interface Application Notes Da Ke 4/5/2009 ECE 480 Spring 2009, Design Team 3 Department of Electrical and Computer Engineering Michigan State University Abstract Java is one of most widely used programming language today due to its openness, ability to scale up and portability. The language is design to have a simpler object model and fewer low-level facilities like pointer methods in C/C++. Sometime this could impose a limitation on what a program can do. This application note will explore various ways of implementation that will allow Java to interact with some programs that are written in lower level language. Keywords: Java, JVM, JNI, Linux, Windows, Operating System, Native interface, Native code Introduction Most modern high level programming languages today are capable of handling what once consider trivial tasks for developers like memory management. However, this doesn't come without cost. A Java application does not interact with underlying system infrastructure directly instead it first compile source code to bytecode and run on Java virtual machine which itself is an application that run on top of the operating system. The Java virtual machine acts like a mediator between the application and the operating system. Most modern implementations of Java Virtual Machine does include several interfaces and libraries that we can utilize to allow Java applications to perform some system level tasks and even speed up the execution of the program by handing over some more resource-intense operations to programs that are runs natively on the machine. Objective This application note will explain different approaches to implement system level functions using Java Programming Language.
